Employers often adopt zero tolerance policies and assume that doing so will give them the right to immediately fire someone for a breach. These are often used for transgressions that are considered particularly egregious, such as harassment. Although we consistently advise employers to address misconduct such as harassment and make it clear that such behaviour is unacceptable, the reality is that courts will not be bound by zero tolerance policies and will conduct their own assessment of whether summary dismissal is warranted. Saying that “we have a zero tolerance policy” will not be the end of the story.
